To aZZ whom it may concern.-

Be it known that I, ALBERT R. CARROLL, a citizen of the United States,residing at J oliet, in the county of \Vill and State of Illinois, haveinvented certain new and useful Improvements in Hinges, of which thefol-lowing is a specification.

My invention relates to the construction of spring-hinges for doors ofall kinds.

The especial object of my invention is to provide a spring-hinge inwhich greater power is obtainable than from hinges of ordinaryconstruction; in which the tension of the spring can be quickly andeasily adjusted as may be desired without the use of special tools; inwhich the adjusting devices are formed as a part of the hinge and arenot detachable therefrom; in which the same form of hinge can be adaptedto either right or left hand doors; in which one leaf'of the hinge mayremain permanently on the door-frame while the other leaf is left on thedoor when the latter is unhinged, thus avoiding the necessity forremoving the attaching-screws; in which the parts can be made bystamping from sheet metal, thus providing economy in the manufacture ofthe hinge, and in which there are no loose parts to become lost ordisplaced and plete, taken from the outside of same. Fig.

2 is an elevation of the hinge-spring and the tension-ad ustingcollarsecured thereon. Fig. 3 1s an elevation of the hinge-leaf shown at theleft hand of Fig. 1, together with the holding device attached to saidleaf. Fig. 4c is an elevation of the other leaf, including the pintleand the collar-locking means secured thereon. Fig. 5 is a top plan viewof Fig. 3. Fig. 6 is a top plan view of Fig. 4 with the pintleremoved,and Fig. 7 a cross-section taken on a line transversely of Fig.1 and at a point through the collar.

Referring to the drawings in detail, 1 represents the hinge-leaf shownat the left hand of Fig. 1 and which is designed to be secured to thedoor frame or casing. This leaf is preferablystamped from sheet metal,with the tubular barrel portion 1, which serves asa housing for thecoiled spring 6 and. which is cut away at 1 to provide a recess oropening to receive the collar 3. The leaf is further formed at its upperand lower edges with bent-over eyevlugs 1, which are adapted to receiveand hold in place the horizontal arms 6 of the spring. It is alsoprovided with a cylindrical portion 1 which serves as a means ofsecuring to the hinge the holding-rod 5. Between the barrel portion 1and the overhanging flanges l 1 of the leaf are openings 1, which permitthe pas sage of the arms of the spring described. Each of the flanges 1is provided with a hole 1 in its center to receive the pintle 7 when thetwo leaves are joined. The hinge-leaf 2 is also stamped from sheet metaland bent to form flanges 2 2 atright angles to the face of the leaf,said flanges corresponding in shape to the flanges 1 l of the leaf 1 andadapted to overlie said last-named flanges when the leaves are assembledto form a complete hinge, as clearly shown in Fig. 1. The flanges 2 2are also provided with suitable holes to receive the pintle 7. Cut andbent up from the body of the leaf are two eye-lugs 2 2 which are spacedapart and form means for connecting to the leaf the collartension-adjuster L, which is slidably mounted in said lugs. The inneredge of the leaf 2 is turned upwardly, as at 2, and has near its edge anopening through which projects normally the hooked end 4 of the adjuster1, as shown in Fig. 7 and as indicated by dotted lines in Fig. 4.

The collar 3, which is mounted in the opening 1 in the leaf 1, is formedwith radial openings 3 and has an opening 3 extending through its upperand lower sides to receive the bent portion 6 of the spring, asindicated by dotted lines in Fig. 2 and in section in Fig. 7. It will benoted that the spring 6 is coiled in one direction for its upper halfand in the opposite direction for its lower half, so that the normaleffect of turning the collar 3 will either increase or diminish thetension of both halves of the spring, depending upon the direction inwhich said collar is turned. The collar-adjuster 4 is composed of apiece of wire bent into the form shown and having the wires broughttogether and bent upon themselves to form the hook 1* at one side andbent up at the opposite side to said hook, as at 4:", to provide agrasping portion for the fingers, whereby the adjuster may be readilyslid back and forth in the bearings provided by the lugs 2 2 The hook 4is of such size as to permit its be ing readily pushed into andwithdrawn from the slots 3 in the collar 3.
